DRAG-HARROW CLEANER.

4Specification of Letters Patent.

Patented July 5, 1921.

Application led. April 19, 1920. Serial N o. 375,031.

To all 'whom t may concern.:

Be it known that I, GEORGE KENDEL, .a subject of the King of Great Britain, a resident of the village of McNutt, Province of Saskatchewan, Dominion of Canada, have invented certainV new and useful Improvements in Drag-Harrow Cleaners, of which the following is a specification.

This invention relates to improvements in drag harrow cleaners, and the objects of the invention are to facilitate cleaning the harrow teeth from weeds, straw and the like, thereby permitting the harrow to perform better work, to provide means whereby the harrows may be vertically displaced to allow the foreign material such as weeds, and

straw collected thereby to be deposited in heaps by gravity, to permit of the desired number of vharrow sections being utilized and each section individually cleaned, and generally to adapt the harrow to better per form the functions required of it.

With the above and other objects in view, the invention consists essentially of theimproved construction particularly described and set forth in the following specification and accompanying drawings forming part of the same.

In the drawings:

Figure 1 is a plan view of a harrow embodying my invention.

Fig. 2 is a rear view of the same with the seat and truck wheels removed for the sake of clarity.

Fig. 3 is a side elevation of the improved harrow cleaner.

Fig. 4L is a perspective view of a portion of a frame showing a guide roller and guard member mounted thereon.

Fig. 5 is a perspective view of a portion of the truck frame.

Fig. 6 is a perspective view of one of the extension bars of the truck frame.

Like characters of reference refer to like parts in the several figures.

Referring to the drawings: A represents the improved drag harrow cleaner comprising a plurality of drag harrow sections l0 the forward ends of which are attached to a bar 1l to which horse or like traction may be attached. This bar 11 is connected to the curvilinear forward ends 12 of the angle bars 13 which are arranged in pairs and converge toward the rear of the machine, each pair of angle bars 13 being connected to a boxing 14 in which is journaled the vertical spindle 15 on the lower end of which the truck wheel 16 is journaled.

A cleaning element 17 is formed on the spindle 16 and is located adjacent to the periphery of the wheel16 and the angle bars 13 are adjustable on the spindle 15 so that the height can thus be altered to suit the amount of lift which is to be given to the rear end of each harrow section 10.

The adjustable means which I provide on the spindle 15 consist of collars 18 which are retained in position by set screws 19. The upper ends of the spindles 15 pass through orifices in the adjustable transversely extending bar 20 which is formed in two sections secured together by collars 21 and this bar 20 can be adjusted to alter the distance apart of'each'bar of the angle bars.

Extending transversely across the angle bars are a pair of spaced bars 22 which are preferably of angle section and these bars are provided with slots 23 through which bolts 24 pass, the said bolts passing through slots 25 in the angle bars 13.

It will thus be seen that the transverse bars 22 can be adjusted on the angle bars 13 to suitd the length of harrow sections 10 being use The bars 22 are provided with a plurality of rollers 26 pivotally mounted thereon and when more than three harrows have to be used extension bars 27 are provided arranged in pairs and rigidly secured to the bars 22, the said extension bars having slots 28 in their vertical flanges to adjustably support rollers 29 between the extension bars.

A frame 3() of rectangular formation is mounted on the bars 22 and strut members 31 are provided having slots 32 therein in which the rollers 33 are adjustably mounted, and the transverse member 34 of the frame 30 is provided with a plurality of orifices 35 in each of which a roller 36 is rotatably mounted.

On the rear face of the transverse member 34e, a guard 37 is mounted and a flexible member 38 passes through the guard and over the pulley 36 around guide pulleys 26 and is attached to a harrow section 10.

It will be understood that each harrow section has a flexible member 38 passing over suitable guide pulleys and through a guard 37 and formed with a ring 39 on the end which is used as a hand grip.

A seat 40 is mounted on the truck frame and the driver has allthe rings 39 adjacent Y to hisV Vhand so that'he can pull whichever `flexible member 38 he desires and a lifting force will be applied to the rear end oa corresponding harrovv section Which elevatesY the said section and thus allows any Weeds, or 'foreign material collected thereon to drop on the ground, so cleaning the harroW teeth and after theharrovv has been dropped to its normal position-the said teeth will be able kto properly function and harrovv the ground.

Each harrovvr section may be elevated and lowered asV oten'as itis necessary to eiiecf` tively clean the harrovv; teeth.

' The harrovv may be 'made of thedesired size With the necessary extension bars to provide for 'a suflicient number of harrovvs being simultaneously operated to suit the require# VVments of the farmer using this device. .Q

vAs many changes vcouldbe .made in the above yconstruction and many Widely difier- What I claim as myA invention is: i 1. A harroW cleaner consisting of a truck ing designed to be secured to the draw bar of a harrovv, an adjustable bar'connecting the rear ends of the angle bars, Wheelslocated at Y soV Vframe having pairs of angle bars converging toward each other, the front of the bars be-V the rear end of the angle bars, a pair of v 2. The harrovv cleaner claimed in claim l, f

in Which guards are located adjacentito the guide membersv and through which guards the f iexible'members extend. i Y' k3. Theharrow cleaner claimedinrclaim l, in which extension bars'areprovidedand connected to thetransverse bars. f

4;.V The harrovvVV cleaner 'claimed in claim l, in which the uangle barsV have longitudinal slots therein and the transverse'spaced bars have longitudinal slotsV therein, Vand, "bolt means extending through the said slots. In Witness whereof I have hereuntoset my hand. Y
